The system is the proficiency panel

The demon tree, which had lost both its wooden heart and its demon pill, was unable to struggle and died quickly. Its death caused tremendous changes in the central area.

The formation that suppressed the paulownia tree was broken, and the spiritual energy of the secret space was quickly absorbed by it. The paulownia tree, which originally looked lifeless, now regained new vitality, and its aura was gradually rising to the perfection of Qi training.

"It probably won't get any stronger. Is that the end?"

Xiao Ningxue looked at the skyrocketing strength of the Wutong tree in front of her. Although it had completed its Qi training like the other demon trees, the pressure it brought to her was incomparable.

As Xiao Ningxue finished her words, a red light suddenly lit up at the bottom of the phoenix tree, and then the entire tree began to burn. The flames did not cause any damage to it, but instead made its momentum even stronger.

Just as the flame appeared, the ancient Wutong tree far away in the center of the Misty Forest suddenly woke up. It sensed the breath of the Phoenix blood and directly used its mental power to cover the Misty Forest to check the specific location.

A ray of light flashed across the sky, and the spiritual power of the ancient Wutong tree extending from the center of the misty forest was completely cut off. The pain that struck the soul directly was so unbearable that the ancient Wutong tree uttered no sound.

"what!"

The ancient Wutong tree cried out in pain, attracting the attention of other monsters nearby, but it endured it and gave orders.

"I'm fine, hurry up and find Feng Tian."

"Yu Shui is still staring at me. His strength is increasing too fast. The Phoenix Blood cannot be lost. Feng Tian must go get it."

While the ancient Wutong tree was repairing the damage to its soul, it was thinking about what to do. Soon, a very beautiful bird with a body length of 10 meters flew in front of the ancient Wutong tree from a distance.

"What's the matter, ancestor?"

"Phoenix blood has appeared in the Misty Forest. With your blood, you can definitely sense its location. Go find it quickly. I will let a demon king protect you in secret. You should also try to avoid the people from Xuantian Sect."

"I understand, ancestor!"

After Feng Tian received the order, he left quickly. His speed was very fast, almost reaching twice the speed of sound, and his cultivation was only at the seventh level of Qi training, which was incredible. Seeing Feng Tian leaving the ancient Wutong tree, he gave orders.

"Qingniao, shrink down and follow him to protect Fengtian. Try not to take action if you can. That person is watching me, and I can't interfere with what's happening outside."

A small green bird on the ancient Wutong tree followed Feng Tian after hearing the order.

……

Within the secret realm.

Although the Wutong tree's momentum surged after the flames appeared, its strength was still at the level of perfect Qi training, which made Lin Ji and Xiao Ningxue breathe a sigh of relief.

Ten large fireballs suddenly condensed around the paulownia tree, and vines and thorns appeared on the ground and attacked Lin Ji and the others. This paulownia tree was more aggressive than the previous demon tree. Lin Ji and the others started attacking when they were still 10 meters away from it.

"Ningxue, you deal with the fireball in the air, and I'll deal with the trouble on the ground and attack its main body."

Lin Ji looked very confident because he could easily cut open the space of the secret realm. As long as the space was cut open, even the three kinds of wood forces of the Wutong tree could pose a fatal threat to it.

Lin Ji condensed his Qi sword and rushed towards the phoenix tree, swinging his sword to chop at the attacking vines, making a sound of metal clashing. The sword only cut more than halfway and could not cut it off completely.

"It's really hard. It really has three kinds of wood power: growth, recovery, and hardness. Fortunately, the phoenix tree is not in the foundation-building stage, otherwise it would have formed the artistic conception of wood. Now I have to use the Sky-Splitting Technique to hurt it."

With this thought in mind, Lin Ji expanded the space-time domain, used the Sky Rift to create a crack in the space, and used the sharpness of the space to cut through the vines. In an instant, the vines that were about to surround him were torn apart by the space, and he continued to move towards the paulownia tree.

In the air, Xiao Ningxue was dealing with those fireballs. She had already deployed a water formation to block those fireballs. After contact, she found that these fireballs contained fire: burning and high temperature. I really don't know how this Wutong tree was cultivated. Those fireballs were so powerful that they could even burn the heavy water used by Xiao Ningxue.

"Master, I leave it to you. I can't handle that fireball."

Xiao Ningxue, who was besieged by fireballs in the sky, did not hesitate and let Yu Yue take over her body. After Yu Yue took over her body, the range of the water array she cast could reach 1000 meters, completely covering the entire battlefield.

"Ningxue, watch carefully how I lower the temperature in the water array. You can experience it very well in this state."

Yu Yue's mind moved, and after a while the temperature that had risen around her due to the burning of the paulownia trees began to drop at a very fast speed, and snow had already begun to fall in the water array.

"Water Array: Extreme Cold!"

With Yu Yue's low shout, the ground in the water array began to freeze, and the fluttering snowflakes in the air turned into a howling blizzard. Yu Yue then controlled the icicles and the fireball to collide with each other, constantly wearing it away. In this environment, the fireball no longer had its previous power, and its size began to slowly shrink.

The flames burning on the paulownia tree dimmed due to the change in environment, and even the vines and roots that were besieging Lin Ji slowed down. However, under Yu Yue's deliberate control, this cold environment did not cause any trouble to Lin Ji.

Thanks to Yu Yue's help, Lin Ji's travel speed has been increased, and he has reached 100 meters away from the phoenix tree. All the way here, Lin Ji has been using the space-time field, but the range is controlled within 5 meters around his body to reduce the consumption of spiritual power. Now Lin Ji still has 8 levels of spiritual power left in his Qi sea.

The paulownia tree was very sensitive to Lin Ji's approach because it could feel the fatal threat posed by the space rift. It relaxed its control over the fireball and began to concentrate on dealing with Lin Ji. The overwhelming vines suddenly increased his pressure. Although they could not hurt Lin Ji, they slowed down his forward speed a lot.

On the other side, Yu Yue had everything under control. The original 10 fireballs were almost unsustainable. Now the Wutong tree had relaxed its control in order to deal with Lin Ji. She found an opportunity to successfully extinguish it and began to help Lin Ji deal with the Wutong tree itself.

With Yu Yue's control, a lifelike ice dragon appeared out of thin air. Its size was comparable to that of the paulownia tree. It crashed directly into the paulownia tree from the air. The power was so great that the paulownia tree had to draw back some of its energy to defend against the ice dragon.

Boom! A huge roar accompanied by shock waves spread in all directions, and the attack of the phoenix tree stopped. Lin Ji found the opportunity and moved forward quickly.

After the ice fog produced by the ice dragon's impact dissipated, the current state of the paulownia tree was revealed. The whole tree was slightly tilted due to the impact, and the flames on the tree were basically extinguished. The trunk that was hit head-on was a little dented and broken, but it was not serious, and it had already begun to slowly repair itself.

"Tsk, it's so hard!"

Yu Yue said unhappily, and then continued to create the Ice Dragon. This was the most powerful move she could safely perform now, and it didn't consume much energy.

Once again controlling the ice and snow in the water array to condense into ice dragons, Yu Yue directly consumed 6 levels of spiritual power to condense three ice dragons, vowing to achieve some results to improve Xiao Ningxue's position in Lin Ji's heart.
